Question

How did you get the characters from your parents and grand-parents?

Answer 1

Hint: The sum of all biological processes by which unique features are passed from parents to their offspring. Two seemingly paradoxical findings about organisms are part of the principle of heredity. The process is done by genes, which define the characters in the organism.

Complete answer:
As is evident in the study of genetics, constancy and variance are simply two sides of the same coin. Genes, the functional units of heritable material that are present within all living cells, may clarify all aspects of heredity. A collection of genes unique to that species is available to any member of a species. It is this set of genes that provides the species' constancy. However, differences can occur among individuals within a species in the shape that each gene takes, providing the genetic basis for the fact that no two individuals (except identical twins) have exactly the same characteristics.
The genotype of the organism is considered the set of genes that an offspring inherits from both parents, a mixture of each one's genetic material. The genotype is contrasted with the phenotype, which is the physical expression of the organism and its genes developmental outcome. The phenotype encompasses the body structures, physiological processes and behaviors of an organism. In distinct combinations, a human gets his set of genes from both his parents. Your parents get their genes from their parents, in turn. The interesting part is that at every stage, this transmission does not remove every gene. The combination just varies. Therefore, you end up looking like them when your genetic combination resembles that of your grandparents.
The characters that were present in our grandparents were transferred from their parents to our mother and father. With the help of gametes that combine during fertilization, the traits are passed on. The mother obtains one set of chromosomes and the other set from the father. During the course of sexual reproduction, the characteristics are transferred to us by our ancestors. This is recognized as the pattern of inheritance by which the characters are passed on and carried on from one generation to the next.

Note:
The distinctions between the parent and offspring in the characters / traits are called variation. Heredity is the transmission of characters or traits from one generation to the next one. Variations between individuals can accumulate through inheritance and cause species to evolve by natural selection. Genetics is the study of inheritance in genetics.
